ShopTo are selling a Tomb Raider "download" for £19.99, does anyone know if it'd be a Steam key? Greenmangaming are also selling it (for the same £26.99 as Steam) and they say it requires a Steam account.

There's a Microsoft Arcade Bundle over at Amazon.com that includes Deadlight, Insanely Twisted Shadow Planet, Mark of the Ninja, Iron Brigade and Toy Soldiers, all on Steam for a paltry $9.99. Or $4.99 if you still have a coupon.
